day this species still nests where it has for years in the chasm 
called “ Purgatory” at the westerly end of the Second Beach, 
Middletown (see Frontispiece); building their nests in the little 
inaccessible crevices of the vertical walls, where they usually

rock. No Cliff Swallows (Petrochelidon lunifrons) breed in this 
chasm, a place apparently more suited to them, than to the Barn 
Swallows.
